Spinning reel with winding drum brake

ABSTRACT

This spinning reel has a winding drum rotated about a normally stationary spool to wind line thereon, and includes a pickup bail pivoted on the drum and spring biased form a casting position clear of the line to a winding position where it engages the line. When placed in the casting position a slidable plunger retains the pickup in casting position while ans associated spring biased, friction brake is applied to prevent accidental rotation of the winding drum. When it is desired to wind in the line, rotation of the winding drum causes a stop member to shift the plunger and thereby remove the friction brake application and permit the biased pickup to move to its winding position.

PATENTEU DECMIBYI B EZKZZB SHEET 1 BF 3 SPINNING WEIIEIL WITH WINDINGIDR UM IHBMAIIGE This invention is concerned with a casting reel.

There are known casting reels which comprise an angularly fixed spool, arotating drum surrounding the spool and a pickup pivoted on this drumand able to be brought from a withdrawn casting position into a pickupposition under the action of the drum's rotation when driven by thefisherman, it passes a certain position corresponding to the position ofa release stop.

In such reels, it often occurs that during casting the drum accidentallypivots which provokes the unwanted return of the pickup into pickupposition. To remedy to this drawback there have already been proposedreels having a device which brakes or stops the drum when the pickup isin withdrawn position.

Some of these reels have a shoe or other braking member fast on the drumand urged against a fixed frictional surface by a spring when the pickupis locked in withdrawn position by a member held by a second spring.Such devices are complicated and therefore costly and subject to goingout of order.

Other reels of this type comprise a bent and pivoted braking memberacting by one of its extremities against the fixed release cam under theurging of a single spring also tending to maintain the other end againsta notch of the pickup in such a way as to prevent the return thereofinto pickup position.

When by voluntary rotation of the drum the fisherman exceeds thefrictional stress of the braking member against the cam he brings thismember to pivot when it meets the release teeth of the cam, which, byliberating the notch of the pickup, permits the tipping thereof.

Nevertheless this arrangement does not give entire satisfaction. Ineffect it does not allow the braking of the drum except from the momentwhen the pickup is locked in withdrawn position. Moreover this directconnection of the braking and locking functions causes a very narrowdimensional tolerance for the mechanism since the braking member,practically held immobile by the notch of the pickup, becomes irregularor inoperative in case the fixed cam goes off center. This explains thefact that the braking member is often made to act upon a cam of smalldiameter which is less likely to have irregularities than a fixed rampof large diameter which would permit, however, for equal tension, a muchmore important braking torque.

Consequently, the invention proposes to provide a reel for casting whichmakes possible a regular and efi'ective braking of the drum when thepickup is in withdrawn position thanks to its simple and foolproofbraking device which does not require particular precisions in itsdimensions.

To this effect, the invention is concerned with a casting reelcomprising an angularly fixed spool, a rotating drum surrounding thespool, a pickup, pivoted on this drum and able to be brought by returnmeans from a withdrawn position to a pickup position, characterized inthat is comprises, a sliding member which is guided by the drum and hasan extremity which can immobilize an arm fast on the pickup, saidsliding member carrying on the one hand a transversal shaft againstwhich can pivot a lever equipped with a braking shoe and urged by aspring in the direction of a cylindrical apron fast on the casing of thereel, and on the other hand a surface permitting the sliding ofsaidsliding member when it meets a fixed return stop of the pickup.

Other characteristics and features of the invention will be laterindicated in the following description which refers to the accompanyingdrawings which illustrate in a nonlimiting fashion:

In FIG. ll an elevation in partial vertical cross section of a castingreel;

In FIG. 2 is a side elevation of FIG. ll;

In FIG. 3, a cross section along III-III of FIG. I which is partiallybroken away to show some of the elements;

In FIGS. 4i and 5 views similar to FIG. 3 for different positions ofcertain elements illustrated in that figure.

The reel shown in the drawing (FIGS. II to 3) and which is intended forcasting comprises a casing 11 in which is positioned a multiplyingdevice on which only the last toothed gear 2 is visible and the drivingof which is possible by the rotation by the fisherman of a handle 3pivotally mounted at the end ofa boss 6 in casing ll.

This multiplying mechanism actuates on the one hand an alternate axialmovement of a shaft 5 at the upper part of which is secured a spool 6and on the other hand the rotation of a drum 7 through the agency of apinion 8 cut at the lower end of a sleeve 9 surrounding shaft 5 andmeshing with toothed gear 2.

This sleeve is pivoted on a bearing 10, for example a roller bearing,mounted in a ring llll of casing I and surmounted by a disc 112 having astop B3 on the face thereof facing drum 7. On the cylindrical apron ofthis drum project two bosses l4 and 113 forming-a support for pickup 116with a guide with which the reel is provided which is only partiallyrepresented in the drawing (FIG. 2). To this efiect, boss 14 is hollowedout with an annular groove ll4a in which fits a spiral return spring 17secured to the drum by one end and to the arm or ear 16a of the pickupby the other. It is by this ear that the pickup is I pivotally mountedrelative to boss Ml, in particular through the agency of a setscrew 18the part of which near its head forms a cylindrical pivoting shoulder.

Arm 116a carries three members: a break 19a defining the pickup positionof the pickup by bearing on a stop 20 of the drum (FIG. 2), a ramp ll9bintended to actuate the axial movement of a plunger 21, for a purposewhich will be indicated later, and a window 19c intended to receive theend of plunger 211 when pickup M has been brought into withdrawnposition, against the urging of spring 17 to allow locking the pickup inthat position.

As shown in the drawing (FIGS. 1 and 3), the plunger 21 is formed of acylindrical rod carrying a pusher constituted by a sleeve 22a projectingat its lower part. This projection is intended to make possible manualactuation of the plunger, from left to right, against a return spring23. This plunger slides axially in the drum through the outer surface ofsleeve 22a and by its right end in a passage in of the hub of the drumand can be brought by spring 23 from inoperative position (FIG. 3) intolocking position of the pickup (FIG. 5) under the urging of thepreviously mentioned spring 23. This spring is stretched between a fixedstud 23a of the drum and a finger 24in on lever 24 pivoted at 24a onplate 25 fast on plunger 23.

Lever 24 has at one end a shoe 26 of rubber or plastic material having aconvex profile the radius of curvature substantially equal to that ofthe inner envelope of a cylindrical skirt 12a on the edges ofdisc 12.

A shoe 26 integral in rotation with drum 7 is in effect intended tobrake this drum when lever 24 is brought into the position of FIG. 3,the shoe 26 rubbing permanently on the ring 12a fast on casing 1.

At its extremity opposite shoe 26, the lever has a beak 241: by means ofwhich it bears on a stop 27 of drum 7 in the posi tion of FIG. 3.

On plate 23 additionally projects a triangular cam 25b extending on thelevel of stop 13 and at a distance from the pivoting axis of drum 7 suchthat if the plunger is in the position of FIG. 5 and this drum isrotated it contacts this stop 13 by means of one of the inclined facesin such a way that it is subjected to a radial push directed towardssaid pivoting axis opposing itself to the action of spring 23 and movingthe plunger in the same direction by an amount sufficient to free theleft hand extremity of this plunger (FIG. 1) from opening 1% of the earof the pickup. Under these conditions the pickup which is subjected tothe urging of its return spring 17 returns to pickup position (FIGS. IIand 2), position which is defined by the meeting of beak ll9a with stop20.

As we shall see, the constructive characteristics of the reel which havejust been described not only allows to proceed to braking the drumsolely when the pickup is in the withdrawn position or when the .drumoccupies only a determined position but already from the moment thatthis pickup has been manually moved away from its pickup position andregardless of the position of the drum at that moment.

For this purpose, when the pickup is in pickup position, the plungerrests at the top of ramp 19b and lever 24 then occupies the positionillustrated in FIG. 3.

When the pickup is actuated to go to the casting position, the arm ofpickup 16a pivots on its axis, ramp 19b no longer contacts the extremityof plunger 21 which results, under the urging of spring 23 and throughlever 24 bearing at 24b to bring shoe 26 into contact with the annulartrack 12a of flange 12 (FIG. 4).

Still under the urging of spring 23, bearing now on show 26, lever 24leaves its bearing point 24b and causes the ascent of plunger 21 throughits shaft 25a until the end of the plunger penetrates into hole [9c ofthe arm of pickup 16a. In this manner the pickup is locked in openposition.

The braking lever, pivoting at 250, urged by the spring, maintains apermanent contact between shoe 26 and braking surface 12a, regardless ofthe potential decentring of this sur-' face relative to the rotationalaxis of the drum. The release of the pickup is effected by contactbetween stop 25b integral with the plunger and fixed ramp 13 integral ofdisc 12. As long as these two elements do not come into contact, theshoe fulfills its braking function. As soon as ramp [3 urges stop 25a,the plunger comes out of hole 190, the shoe remaining in contact withring 12, thus frees the pickup which closes under the urging of returnspring 17. The end 24b of lever 24 comes to bear against boss 27, cam19b acts on the extremity of the plunger causing the movement of theshoe away from the frictional surface 12a of tray 12. The antiinertiabrake no longer touching the handle of the reel.
